I have this problem too when several videos are running at the same time, and the only way I found to fix it is to disable hardware acceleration in Flash settings by right clicking on a video and click Properties. Then I refresh the pages and the videos plays well.

update: still get green screen when demanding multi-video running[/quote]
To avoid the green screen and driver crash when playing several videos, I just disable the hardware acceleration in flash.

But it appens also sometimes when for example I'm watching TV on Windows Media Center and launch an MKV in Media Player Classic with CoreAVC CUDA video decoding, the driver stops responding and Windows reloads it, but as the videos continue it stop again and again. I have to press ALT+F4 to close MPC and let the driver reload properly.

I have these problems since drivers 25x.xx, it don't happen too often but it's annoying as my GTX260 get stuck in 2D frequencies after driver reload, so games are on low FPS and I have to reboot to get the correct 3D frequencies in games.
Maybe I'll try back drivers 1xx.xx.

I got bored with this bug, anytime I watch TV in Windows Media Center on my 2nd screen and play some video on some games sites (IGN, GameSpot, ...) or in Windows Media Player the driver crashes, even with the Flash hardware acceleration disabled.

So I got back to the 197.45 for Windows 7 x64 (after uninstalling the 258.69 and running DriverSweeper under Windows' safe mode), and now I can launch several Flash videos with Hardware Acceleration enabled, Windows Media Center, Windows Media Player, ... Everything runs smoothly with these drivers, no crashes.

I'll wait for future working version before coming back to 2xx.xx series. Nothing really useful were added for my computer personal usage.

Yea same here, I love the fast loading time in a games like bad company 2 but the constant crashing watching tv shows or movies and crashing wasn't worth it. I wish the would get it fixed soon. So I can load with all the rest of my friend with ATI cards.
